GEORGE DRAPEIL OF HOPEDALE, MASSACHUSETTS.

Specification forming part of Letters Patent No. 134,863, dated January14, 1873.

To all whom it may concern:

Be it known that I, GEORGE DRAPER, of Hopedale, of the county ofWorcester and State of Massachusetts, have invented a new and usefulImprovement in Bing- Spinning Frames, or in mechanism thereof; and dohereby declare the same to be fully described in the followingspecification and represented in the accompanying drawing, of which-Figure 1 is a front elevation, and Fig. 2 a vertical section, of aring-spinning-frame spindle, its step and bolster-standard provided withmy inventiomwhioh has special reference to a spindle bolster and bobbinarranged on what is termed the Sawyer plan, the main or principalfeatures of which are described and represented in the United Statespatent N 0. 113,575.

In the Sawyerspinning mechanism the bolster or bolster-standard extendsup within the bobbin, the spindle going'up through the said standard andentering and supporting the bobbin. To oil the bolster has requiredeither the raising of the bobbin sufiiciently above the bolster or theformation of the bobbin with one or more oiling-passages made laterallythrough or in it, just above the bolster or at the head of thebolster-chamber of the bobbin.

To avoid the difficulties attendant upon or incident to such modes ormeans of effecting the necessary supply of oil, and also to enable theoiling to be done while the spindle may be in revolution, are objectsIhave had in view in making my invention; Another purpose has been toshield or protect the lubricated surfaces and oil holding or receivingspaces from dust, fibrous filaments, or extraneous matters, as well' asto properly support the spindle in order to enable the bobbin to beremoved therefrom without at the same time lifting the spindle, all ofwhich objects orpurposes have been fully attained by my improvedspinning mechanism.

In the drawing, A denotes the spindle; B, the bolster-standard; C, thebobbin; 1), the whirl; E, the step; F, the bolster-standardsupporting-rail; and G, the step-rail. The bolster-standard, at itsfoot, is chambered, as

shown at a, the chamber being cylindrical in shape and open at bottom.Within this chamber there is placed a cylindrical cup or oil-reservoir,I), concentric with and fixed or fastened to the spindle so as torevolve therewith and be revolved thereby when the spindleis inoperation, the said cup having a diameter a very little less than thatof the chamber a. From the bottom of the bushing a: of the bolster, suchbushing being extended down into the oil-cup b, as shown, there leadsupward around the spindle and in the bore of the bolster standard orb'ushing, and through the bolster or upper bearing 0, one or morehelical grooves, d,- and there is formed in the head of the standard Ban oil-receivin g channel or annular cup,

0, concentric with and to encompass'the bolster or upper bearing 0. Oneor more passages, f, lead from the bottom of the receiver 0 into thebore of the bolster. Furthermore, in the base of the standard B or belowthe bobbin there is an inclined oil-educ-t or supply-passage, 9, leadinginto the bore of the standard and provided with a cap or cover, It, toslide freely up and down upon and fit to the bolsterstaudard. The whirlD is chambered in its lower side and around the spindle, such beingshown at i, and to receive a tubular extension, k, of the step E. Thesaid tubular extension encompasses the spindle, whose pivot is at thebottom thereof, there being a hole, It, to lead from the oil-reservoirof the step into the space or chamber at of the extension. An annularcap or cover, it, encircles the extension and fits upon the step, asshown. On raising the said cover and pouring oil into the space Z suchoil will run therefrom through the passage is into and upon thestep-bearing of the spindle. By the extension 7.: going up to or withinthe whirl the stepbearing of the spindle becomes thoroughly protectedfrom dust and fibers or filaments of the cotton or material while beingspun. Furthermore, 011 raising the cap it on the bolsterstandard andpouring oil into the induct g, such oil will run into thebolsterstandard, from whence it will be elevated by the helical groove dwhile the spindle is revolving, the oil being carried up to and throughthe bearing a, thence over its top into the reservoir 6, from which itwill flow through the educts f back into the bolster-standard. Thus itwill be seen that the upper bearing of the spindle will be effectuallylubricated by the oil received, as set forth, through the induct g, or

discharged upon the spindle or into the bore of the standard through thesaid induct. The cup 1) within the chamber a answers to-catch andholdthe oil when the spindle is at rest, and also to prevent the spindlefrom being lifted when an attempt is made to raise the bobbin 0d thespindle, the chamber a serving also to protect the cup from dust andfilaments.

I herein make no claim to a spindle-step constructed and havingappurtenances as shown in Letters Patent No. 114,536, dated May 9, 1871,and granted to me, which,though insome respects analogous to my presentstep,has no extension leading up to the whirl, or into a chambertherein. Nor do I claim any thing, combination, or arrangement shown inthe United States Patent No. 122,705, granted to L. Gheetham, whereinthe bolster-standard is shown as provided with an oil-groove and inductat its base, and also with a helical groove extending around thespindle, a groove down the outside of the bolster-standard, and atubular cap to fit to the latter. I avoid any groove down thebolster-standard, and any tubular cap to go around such standard, havingat the top of the standard the oil-receiver e and its educt f, all asdescribed.

The helical groove or oil-elevator may be formed in the spindle insteadof in the bore of the bolster, or there may be such a groove in each.

I would observe that, by having the cap n and the tubular extensionseparate from the whirl, so as not to revolve with it, and arrangedtogether and with the oil-receiver l of the step, as described, the stepmay be supplied with oil while the spindle and whirl may be inrevolution, which is not the casewith the construction shown in the saidpatent No. 122,705, which requires the spindle and whirl to be stoppedbefore oil can be poured into the step. I

Instead of the whirl being used to cap or cover the tubular extension k,there may be a disk fixed to the spindle in the proper place, and suchdisk may be recessed to receive the upper part of the extension; inwhich case the whirl, separate from the disk, would be arranged above itin the spindle. In Fig. 3 I have shown such a construction, which may beconsidered as equivalent for that heretofore described, a in such figurebeing the whirl, b the spindle, c the disk, and k the tubular extensionof the step.

I herein make no claim to a step having a dome, oil-spaces, and a cap,as shown in the patent of Sawyer, dated August 27,1871. Nor

do I herein claim a step capped and having the cap covered in manner asshown in my patent of April 6, 1869, the cap in such case beingstationary, and provided with an oil-hole or inlet.

In my present step I have the two communicatin g oil-receivers, with acover to the outer of them; and, instead of a dome to the'inner receiverI have a tubular extension, k, whereby new and useful efl'ects result;my present invention or improvement in the step being designed toovercome difficulties incident to the step as represented in the saidpatent of Sawyer, and as covered by patent No. 114,570, granted toGeorge William Knight and myself, May 9, 1871.

In practice it has been found that the cap or cover is liable to rise onthe dome and work out of center, so as to leave the outer receiving oilspace more or less uncovered"; or if raised by an attendant for thepurpose of enabling oil to be poured into the receiver the annulus orcover will slip laterally or sidewise on or over the dome. When droppedby the attendant after oiling the cover is liable to fall out of place,or take an inclined position,

whereby it will leave the step more or less open. By dispensing with thedome and using the tubular extension the cover, while being raised,always moves vertically; and while dropping to its seat will be guideddown to place. far as the cap or cover is concerned, is productive ofnew advantages. Furthermore, it has been found that the driving-band,-on slipping off the whirl, will be drawn against the spindle, wherebythe latter will suddenly have its velocity greatly increased, to thedetriment of the spinning operation. By having the extension k carriedup to the whirl, or into a chamber in it, as shown, the band, onslipping off the whirl, will fall upon the extension without coming incontact with the spindle and revolving it.

The tubular extension also protects the butt of the spindle, or the partbelow the whirl, from the loose yarn liable to accumulate on it when itis uncovered.

What I claim as my invention is as follows that is to say:

The bolsterstandard B and the spindle A, provided with the oil receiver0, educt f, helical oil elevator or groove d, oiling-induct g, and therotary oil-reservoir b, the latter being fixed to the spindle, and alsobeing arranged substantially in manner and to operate as specified.

2. The oil-reservoir b, fixed to the spindle so as to revolve therewith,and arranged within a chamber, a, in the foot of the bolster-standard,all being essentially as shown and described.

3. The step provided with the communicatin g oil-chambers l m, thetubular extension 70, and the cap n, all arranged essentially asspecified and represented.
